542 CHAPTER 49: AAA & RADIUS & HWTACACS CONFIGURATION
Symptom 3: The user passes the authentication and gets authorized, but the
accounting information cannot be transmitted to the RADIUS server.
Possible reasons and solutions:
■ The accounting port number is not properly set - Be sure to set a correct port
number for RADIUS accounting.
■ The switch requests that both the authentication/authorization server and the
accounting server use the same device (with the same IP address), but in fact
they are not resident on the same device - Be sure to configure the RADIUS
servers on the switch according to the actual situation.
